Members of a gun forum are not representative of all gun owners. Most people just want a gun to shoot or to carry. They don't care about factory correct finish. And most, in my experience, don't want a gun that looks trashed.
A few years ago, I bought a Model 10-8 from Buds. You know the story, sight unseen. I accepted the gun, but the finish bothered me. I would say 70% remained, with lots of scratches. I think I paid $300 or so for the gun. I had it reblued by a local shop. Looks beautiful now. The reblue cost me $250. If I sold it, would I get $550? I don't know. But so what? The gun looks great now and I have enjoyed it more since I bought it. If I lose $150 in a sale I couldn't care less. Think of all the dumb things we waste money on. I'm not gonna worry about a few cents a day the reblue cost me over the life of the gun.
I'd buy a refinished gun over a beater any day of the week. Would I pay as much for a refinished gun as I would a factory original mint gun? Of course not. The fact that somebody paid to refinish the gun means they probably cared for it mechanically as well. The guy who stored the gun in a leather holster for years clearly didn't properly maintain the gun.
